FIELD: catalysts.
SUBSTANCE: nanostructured catalyst for oxidative dehydrogenation is proposed, comprising a carrier consisting, wt.%: 25.0-55.0 aluminosilicate tubes, 25.0-55.0 ordered mesoporous silicon oxide and up to 100 aluminium oxide, as well as chromium oxide, taken in amount of 1.0-9.9% in terms of metal from the weight of the carrier, whereas aluminosilicate nanotubes with ordered mesoporous silicon oxide form a single structured composite, in which ordered mesoporous silicon oxide is reinforced with aluminosilicate nanotubes, and chromium oxide is evenly distributed on the outer surface and in carrier pores.
EFFECT: increased resistance of the catalyst to deactivation at high temperatures by increasing the thermal stability of the catalyst due to the reinforcement of mesoporous silicon oxide with aluminosilicate nanotubes.
